本文介绍了一个使用ShiroDbRealm实现的身份验证与授权过程。通过整合Spring和Shiro框架，文章详细展示了如何自定义Realm来处理用户登录及权限检查，并配置了ShiroFilter拦截器以实现细粒度的安全控制。

[size=x-large][color=black][b]ShiroDbRealm.java 代码如下[/b][/color][/size]

public class ShiroDbRealm extends AuthorizingRealm {

    @Resource
    private UserService userService;

    /**
     * 认证回调函数,登录时调用.
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authcToken) throws AuthenticationException {
        UsernamePasswordToken token = (UsernamePasswordToken) authcToken;
        User currentUser = userService.findByUserName(token.getUsername());
        if (currentUser != null) {
            if (currentUser.getStatus()==User.STATUS_DISABLED) {
                throw new DisabledAccountException("用户已注销");
            }else if(currentUser.getStatus()==User.STATUS_NOT_ACTIVE){
                throw new DisabledAccountException("用户未激活");//这里需要编写一个用户未激活异常
            }
            return new SimpleAuthenticationInfo(currentUser.getUsername(),currentUser.getUserpwd(), "");
        }
        return null;
    }

    /**
     * 授权查询回调函数, 进行鉴权但缓存中无用户的授权信息时调用.
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(
            PrincipalCollection principals) {
        // Cache<Object, AuthenticationInfo> authenticationCache =
        // getAuthenticationCache();
        String primaryPrincipal = (String) principals.getPrimaryPrincipal();
        System.out.println("-----------*************************------------>"+ primaryPrincipal);
        List<String> roles = new ArrayList<String>();  
        List<String> permissions = new ArrayList<String>();

        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();

        User user = userService.findByUserName(primaryPrincipal);
        if(user != null){
            for (Role role : user.getRoles()) {
                roles.add(role.getName());
                for (Permission p : role.getPermissions()) {
                    permissions.add(p.getPrivilege());
                }
            }
        }else{
            throw new AuthorizationException();
        }
        //给当前用户设置角色
        info.addRoles(roles);
        //给当前用户设置权限
        info.addStringPermissions(permissions); 

        return info;
    }
}
